The utility companies in Pakistan resorts to routine load shedding as a result of persistent energy crises that has become a long term issue. In order to get relief during load shedding, domestic/residential consumers use UPS with battery backup as a means for powering bare minimum load, mainly consisting of light bulbs and ceiling fans. According to an estimation made by Federal Environment Protection Agency, almost 60% of Pakistani domestic consumers rely on UPS with lead-acid battery as electricity backup and an estimated Rs 30 billion is spent by Pakistanis every year on these backup devices that have flooded the markets. The cost of batteries and its maintenance have imposed a financial burden on consumers using UPS. Furthermore, environmental issues and risks of accidents associated with batteries are also of major concern. A survey was conducted to collect information regarding the use of UPS with battery backup, highlighting the issues related to the technical and economic issues and its impact on consumers. In the present work a detailed study on commonly used local manufactured batteries has been conducted and a cost and load model of Battery/UPS system has been developed. Based on the techno-economic study and green energy concept, a novel idea based on pump-storage hydroelectric (PSHE) scheme to eliminate batteries with UPS has been investigated. Amongst the green energy systems, hydro resources seem to be more promising as compared to wind and solar because of their intermittent nature and their availability at sites. PSHE system is a low cost alternate source of electrical energy based on green energy is therefore essential to replace batteries in UPS system. The prototype model was design to exclude batteries from use with UPS which provide consumers with low cost and reliable option. A comparative techno-economic analysis with UPS/battery backup and PSHE/UPS system has been performed. The power supply system, using PSHE to replace the battery can effectively overcome the inherent defects in wind-solar hybrid system. The project was sponsored by Directorate of Science and Technology (DoST) with the plan to commercialize the project as a cost-effective product (manufactured locally) to the consumers during load shedding and for locations such as remote villages hit hard by load shedding.

قندیلِ محبت کے دیے نعت کے الفاظ


قندیلِ محبت کے دیئے نعت کے الفاظ
چمکے ہیں دل و جاں میں مرے نعت کے الفاظ

آیاتِ مقدُس میں ملے نعت کے الفاظ
قرآن کے الفاظ بنے نعت کے الفاظ

دل اہلِ قلم کا ہوا سرشار خوشی سے
قرطاس پہ جس وقت لکھے نعت کے الفاظ

گل ہائے عقیدت کی ہے مہکار سرِ بزم
پھولوں کی طرح لب پہ کھلے نعت کے الفاظ

اس مشقِ سخن کی ہے جزا کوثر و تسننیم
میزان پہ خود بول پڑے نعت کے الفاظ

اعمال کے دفتر کی مجھے خوب خبر تھی
بخشش کا وسیلہ ہی بنے نعت کے الفاظ

الفاظ کی پرواز کوئی جامی سے پوچھے
خود جا نہ سکے اُڑ کے گئے نعت کے الفاظ

بوصیریٔ بیمار شفا یاب ہوئے تھے
جب جانِ مسیحاؐ نے سُنے نعت کے الفاظ

اللہ کی رحمت نے کیا صاحبِ دیوان
عرفانؔ کی خواہش تھی کہے نعت کے الفاظ

أثر مؤشرات التغري املناخي يف انتشار بعض اإلمراض املعدية يف حمافظة ذي قار

The study examines the impact of climate change on the spread of some diseases in Thi- Qar Province through collecting and analyzing data about various weather elements and phenomena of some monitoring stations ( Nasiriyah ) for a high-temperature climatic cycle of 78 years (1941-2018). It is divided into seven consecutive and different time periods, 1941-1951, 1952-1962, and 1963-1973, 1974-1984, 1985-1995, 1996-2006, 2007-2018. These elements and phenomena are solar radiation, temperatures (maximum and minimum), wind (Dust storm, rising dust, suspended dust), and the thermal extremes phenomenon (heat and cold waves) The research aims to reveal the reality of trends in climate of the province of thi qar, and find out the reality of the general trend of the elements of climatic different by relying on a series of evidence statistical number of climatic variables for the meteorological station in Nasiriyah especially temperature, wind speed, relative humidity and rainfall, and extreme dust The most important results of the research showed that temperatures trending upward in sync with a clear reduction in the amount of relative humidity and rainfall which threatens a sharp repeating the phenomenon of drought in the future. The research study has found that the City of Nasiriyah ranked first in human diseases for the period 2009-2018, as the reasons for this level of diseases include that Nasiriyah is subject to the recurrence of dusty weather phenomena due to its proximity to the Western Desert Plateau, as well as the lack of cultivated and water-covered areas. This city witnesses serious air pollutions due to the concentration of a large number of factories located near inhabited areas, as well as, the spread of brick factories in the regions of the city, such as, brick factories in the area of El-Islah. This is public services, in addition to the building projects, deterioration of sewage overflow, the spread of epidemics and insects harmful to human health, other climatic environmental pollutants, such as the spread of pollen, plant scents and air allergens, which contributed to the increase in the severity of skin diseases, climate eyes, arthritis and respiratory allergies. The city of Al-Shatra ranked second in the number of people with climatic diseases, Al-Rifai ranked third with infected cases, Souk Al-Shuyoukh ranked fourth, and finally Al-Jibayish ranked fifth and last in people with climatic human diseases for the period 2009-2018 in Dhi- qar province due to the same geographical, climatic, medical, and environmental causes indicated earlier.

The Impact of Terrorism on the Economy of Pakistan

Terrorism has negatively affected growth & development and forced an intense economic burden on the economy of Pakistan. The general loss of self-assurance in economy resulting helplessness to catch the attention of foreign investors and high defense & security expenditures leads to economic distortions which further affect the economic growth and instability in the country. The objectives of the study are to analyze empirically the long run impact of terrorism on foreign direct investment and economic growth along with other macroeconomic variables (human capital, inflation rate, capital domestic investment, population growth rate, trade openness and unemployment rate and exchange rate) in Pakistan during 1980-2014. To measure the short run relationship between the dependent and independent variables of the models. To explores the influencing directions between macroeconomic variables, terrorism, economic growth and foreign direct investment of Pakistan and to make appropriate suggestions for suitable policy implementation for problems arising from the terrorism in the light of finding of the study. Both primary and secondary data have been used to achieve the desired objectives of the study. Furthermore, For checking stationarity, Unit Root Analysis (Augmented Dickey Fuller test) was used, the Autoregressive Distributed Lag approach to cointegration was used to detect the existence of long run relationship among the variables, and for short run relationship, an Error Correction Mechanism (ECM) was estimated. Vector Auto Regression (VAR) was used to summarized the causality among terrorism, economic growth and foreign direct investment. The Impulse Response Function (IRF) and the variance decomposition was used to analyze the dynamic impact of the random errors on the variable’s system. The main findings of the study are; all the variables except foreign direct investment, terrorist attacks and economic growth are non-stationary at level but at first difference they became stationary. The Autoregressive Distributed Lag approach to cointegration estimation reveals a long term relationship amongst the (i) economic growth and Independent Variables i.e. terrorist attacks, foreign direct investment, human capital, inflation rate, capital domestic investment, population growth rate, trade openness and unemployment rate (ii) foreign direct investment and Independent Variables i.e. terrorist attacks, economic growth, human capital, inflation rate, capital domestic investment, trade openness and exchange rate; for the time period of 1980-2014. Error Correction Mechanism (ECM) models validates that there exists a short run equilibrium relationship among the variables. And the sign of coefficients of terrorist attacks and human capital are in negative which means variables are having negative relationship in short run and are significant in explaining GDP. Foreign direct investment have negative relationship with terrorist attacks, Economic growth, exchange rate, human capital, inflation rate, capital domestic investment and trade openness which is indicated by the negative sign of coefficients of these variables. The coefficient of error correction term is negative and highly significant in both the model. The R-square value is less than Durbin Watson statistics therefore models are not spurious and the models are acceptable. There is no serial correlation and no heteroskedasticity in the both models and the residuals are also normally distributed in both models. It is found from the Impulse Response Function analyses that when one positive standard deviation shock or innovation is given to terrorist attack, it will take approximately 20 years to absorb the shock. Similarly, foreign direct investment will took almost 27 years for absorption of innovation or shock and economic growth will take almost 18 to 20 years to absorb the shock or innovation. The results of Variance decomposition analysis showed that the response of terrorist attack, economic growth and foreign direct investment to the impluses or innovation introduced mostly explained by itself. The negative impact of terrorism on the economy is proved beyond doubt from the findings of the present study and countless other studies, hence it is of the most importance that scourge of terrorism be rooted out from our society. The efforts are required to develop the terrorism affected areas by establishing some useful incentive systems, for-instance, tax free zones to encourage the businessmen and investors to set up their businesses in the terrorism affected regions. Attempts are required to establish various departments or organizations in the terrorism affected areas to provide the local population different job opportunities, quick deliverance of aid, standard school meetings, hospitals with all facilities and the social associations should be developed, in order to build friendliness and trust linkage between the population and government. Emphasis should be given to the children and youth education especially in these affected areas or various kind of creative, Technical and skill trainings should be given to the youth so that they can’t be easily hired by these terrorist groups. Attempts are required to support the crisis‐affected farmers in the shape of agricultural & farming inputs (for instance, fertilizers and seeds) the microcredit and fixing, repairing, availability of quality seeds and improving of irrigation systems.
